Title: Smart card for offline meal plans
Inventor: WILHOIT FRANK ELDON III
IPC: G06Q30/06
Filed: 1998-10-09
Abstract: This invention involves the use of smart cards configured with data indicating a specific meal plan for use in the food vending industry. Examples of typical applications are student meal plans purchased in college or other school systems where the user purchases a plan allowing the user to eat specific meals or at specific times. Usually the meal plan is purchased at the beginning of the school term and terminates at the end of the school term. The invention uses a memory based smart card that is preconfigured on a specific date. The smart card contains data such as the meal plan type, the expiration date of the plan, the last transaction date, the user's weekly quota of meals, the number of meals a user can eat in a day, the user's daily quota and the operator identification. The smart card is confined by a computer at the start of the meal plan. Smart card readers are used to update data on the smart card and decrement existing data as the user purchases meals.

Title: Hydraulic fracturing of ore bodies
Inventor: JEFFREY ROBERT GRAHAM JNR
IPC: E21C37/12
Filed: 1999-02-26
Abstract: The specification discloses a method of mining that makes use of hydraulic fracturing. The method comprises fracturing an ore body hydraulically by introducing fluid rapidly into a bore or fissure in the ore body such that pressure in the bore or fissure builds up rapidly and it fractures. This enables the ore body to cave into a suitable space such as an undercut from which the ore can then be recovered. The method is particularly useful in block caving as a replacement for explosives.

IPC: A61P17/02
Filed: 1998-01-09
Abstract: The present invention relates to use of dichlorobenzyl alcohol for preparing a preparation for topical treatment of inflammation and the preparation for this purpose. It is known to use dichlorobenzyl alcohol (2,4-DCBA) as an agent against bacteria and fungi, i.e. as a desinfectant. By the present invention it has, however, suprisingly turned out that dichlorobenzyl alcohol, preferably 2,4-dichlorobenzyl alcohol, is also useful for treatment of inflammation. The invention also relates to a preparation containing dichlorobenzyl alcohol, preferably 2,4-dichlorobenzyl alcohol, for topical treatment of inflamation, which can be applied onto skin or mucosa in the form of an ointment, a cream, a gel or a solution. Thus, the preparation has turned out to be effective against a variety of inflammatory conditions including skin diseases, such as pruritus and psoriasis, insect bite/sting etc.

Inventor: JOSHI GIRISH
IPC: C07C29/152
Filed: 1999-07-13
Abstract: Methanol emissions in the CO2 vent from a synthesis gas unit in an ammonia or hydrogen plant are reduced by contacting raw synthesis gas from a low temperature shift converter with recycled stripped condensate to absorb methanol. The synthesis gas is treated in a purification unit to form the CO2 vent of reduced methanol content. The condensate from the contacting step is steam stripped to form a process steam stream suitable for feed to the reformer and a stripped process condensate stream suitable for offsites polishing, a portion of which is recycled for contacting the raw synthesis gas.

Inventor: WHITE ANTHONY MICHAEL
IPC: H01L27/146
Filed: 1999-12-03
Abstract: A noise reduced photon detector incorporates an array (10) of semiconductor diode detector elements (12). Each element (12) has an extrinsic active layer (20) sandwiched between two layers (18, 22) of wider bandgap and mutually opposite conductivity type. These layers are in turn sandwiched between two further layers (16, 24) of wider bandgap than the active layer (20) and of higher doping than the other layers (18, 22). A mirror (34) extends round much the array (10) and isolates each element (12) from photons emitted by other elements (12). In operation the elements (12) are reverse biased and exhibit negative luminescence which reduces their photon emission.  These two effects reduce unwanted photon generation and absorption, and consequently photon noise is also reduced.
